ATV6B0C50T6 is a 550 HP normal-duty / 450 HP heavy-duty variable speed drive from the Altivar Process ATV600 series. Rated line current 434 A normal duty, 355 A heavy duty at 600 V — matches a 550 HP motor at 600 V three-phase. Apparent power delivered is 451 kVA normal, 369 kVA heavy. Integrated EMC filter meets IEC 61800-3 category C3 for 300 m shielded cable. No external filter needed for most industrial installations with screened motor leads up to that length. THDI < 5 % IEEE 519 at full load, so harmonic compliance is built in. Safe Torque Off SIL 3 is standard — no need for a separate safety relay or contactor for STO functions. Protection set includes thermal, motor phase break, DC bus overvoltage, ground fault, and overspeed.
Cabinet mount, forced convection cooling. Accepts slot A communication modules: Profibus DP V1, PROFINET, DeviceNet, Modbus TCP/EtherNet/IP, CANopen (RJ45 or SUB-D 9), and CANopen screw terminals. Also supports digital/analog I/O extension and output relay modules on slot A or B. Switching frequency adjustable 2–4.9 kHz with derating. Operates from 50/60 Hz supply, ±5 %. Altitude derating starts above 1000 m; max operating altitude 2000 m. Pollution degree 2. Electrical connections: control uses removable screw terminals 0.5–1.5 mm² (AWG 20–16). Line side screw terminal, motor side M10 x 2 bars.
